Dual-purpose phone case serves up extra power and extra protection. The sleek Power Flip Case pleases the eyes and punches up your battery with a 1,150 mAh power boost when it’s wrapped around your HTC One max. A device battery icon shows up when the full-screen protective case is in use, and a green LED display indicates when both your case and phone are fully charged. Designed to protect, built to perform, and intended to make your friends jealous.
